Ce culot est rendu solidaire d'un étui combustible à l'aide d'une rondelle disposée dans une gorge d'un prolongement axial du culot.This base is made integral with a combustible case with using a washer arranged in a groove of a axial extension of the base.
Le principal inconvénient présenté par un tel dispositif est que le culot ne peut être fixé à l'étui qu'avant chargement de celui ci en poudre.The main disadvantage presented by such a device is that the base can only be attached to the case before loading of this powder.
Tout démontage ultérieur du culot s'avère par ailleurs impossible sans démontage du projectile et retrait de la poudre.Any subsequent removal of the base also proves impossible without dismantling the projectile and removing the powder.
On connaít également par le brevet US5048421 un culot qui se fixe par vissage sur une extrémité filetée de l'étui combustible.We also know from patent US5048421 a base which is fixed by screwing on a threaded end of the case combustible.
Cependant une telle solution est complexe puisqu'elle impose la réalisation d'un étui comportant une partie filetée, qu'il est difficile d'obtenir de façon fiable à partir d'un étui en matériau combustible tel que du carton imprégné de nitrocellulose.However, such a solution is complex since it requires the realization of a case comprising a part threaded, which is difficult to obtain reliably at from a case made of combustible material such as cardboard impregnated with nitrocellulose.

Le vissage de l'écrou 20 sera assuré à l'aide d'un outil
approprié. On prévoira de préférence des trous réalisés dans
l'écrou parallèlement à son taraudage et permettant d'engager
dans l'écrou une clé à griffe de type connu.The
Le moyen support 18 portera également des moyens d'allumage pyrotechnique pour le chargement propulsif, notamment un initiateur 21 (tel une amorce) et un ou plusieurs relais.

Le montage de la munition 1 se réalise de la façon
suivante :
On fixe le projectile (non représenté) à l'étui par un moyen approprié par exemple une bague de liaison telle que décrite par EP307307.The projectile (not shown) is fixed to the case by a suitable means for example a connecting ring such as described by EP307307.
On solidarise l'étui 2 et la cuvette 8, cette dernière
portant la pièce intermédiaire tubulaire 12.The
Le chargement en poudre propulsive est réalisé en
introduisant les grains de poudre au travers de l'ouverture
22 de la cuvette 8.The propellant powder is loaded in
introducing the grains of powder through the
Lorsque le chargement de poudre est terminé on visse
l'allumeur / moyen support 18 sur la pièce tubulaire 12.When the powder loading is finished we screw

l'écrou 20.Finally, the
A titre de variante, on pourra avantageusement fixer par
collage la pièce tubulaire 12 et la cuvette 8 ou encore
réaliser ces deux éléments d'une seule pièce.As a variant, it is advantageously possible to fix by
bonding the
La figure 6 montre ainsi une cuvette 8 dans laquelle la
pièce tubulaire 12 et la cuvette 8 forment une seule et même
pièce en matière plastique. Le taraudage 14 est destiné à
recevoir le moyen support (non représenté). Plusieurs trous
latéraux 22 sont réalisés. Les trous 31 sont destinés à
recevoir les rivets 10 de fixation de l'étui 2.FIG. 6 thus shows a
On pourra également faire varier le nombre de trous
latéraux 22 réalisés dans la cuvette 8.We can also vary the number of
Les figures 4 et 5 montrent ainsi une cuvette 8
comportant quatre ouvertures 22 régulièrement réparties
angulairement et qui sont délimitées par des bras radiaux 23
qui convergent vers une collerette annulaire axiale 24.Figures 4 and 5 thus show a
La collerette axiale 24 porte l'ouverture axiale 11
destinée à recevoir la pièce intermédiaire tubulaire. Comme
dans le mode de réalisation décrit en référence à la figure
2, la cuvette 8 comporte des languettes 17 destinées à
permettre la fixation de la pièce intermédiaire tubulaire.The
Ce mode de réalisation de la cuvette permet d'une part de
faciliter le chargement en poudre en augmentant le nombre
d'ouvertures 22 et d'autre part de donner une certaine
souplesse au dispositif de fixation du culot, souplesse
conférée par les bras 23.This embodiment of the bowl allows on the one hand to
facilitate powder loading by increasing the number
of 22 openings and on the other hand to give some
flexibility to the base fixing device, flexibility

Les figures 7 et 8 montrent un troisième mode de réalisation d'un dispositif selon l'invention.Figures 7 and 8 show a third mode of realization of a device according to the invention.
Suivant ce mode de réalisation l'étui 2 comporte un fond
combustible 2a formant cuvette. Ce fond présente une
ouverture axiale 11 dans laquelle est fixé le moyen support
18 à l'aide d'une pièce intermédiaire qui est constituée ici
par une bague 25.According to this embodiment the
La bague 25 est visible plus en détails aux figures 8a et
8b. Elle est réalisée en matière plastique (par exemple en
polyamide) et a une forme cylindrique. Elle comporte un
taraudage axial 26 qui s'étend sur toute sa hauteur. Elle
comporte au niveau d'une de ses extrémités une gorge
annulaire 30 et quatre becs 27 régulièrement répartis
angulairement et séparés par des fentes radiales 28.The
Les becs présentent tous un chanfrein conique 29 qui
facilite l'introduction de la bague dans l'ouverture 11 de
l'étui.The beaks all have a
Lors de ce mouvement d'introduction, les becs peuvent se
déformer radialement de façon élastique. Le rebord de
l'ouverture de l'étui 2 peut ainsi se positionner dans la
gorge annulaire 30. Le retour des becs en position non
déformée assure l'emprisonnement du rebord de l'étui dans la
gorge 30 et ainsi la solidarisation de la bague 25 avec
l'étui.During this introduction movement, the spouts can
deform radially elastically. The ledge of

précédemment au moyen support 18 avec un écrou 20.Then position the
Il est bien entendu possible de combiner les différents modes de réalisation décrits précédemment.It is of course possible to combine the different embodiments described above.
On pourra par exemple utiliser une bague telle que
décrite en référence à la figure 7 avec une cuvette 8 en
matière plastique telle que décrite à la figure 1. Il sera
alors inutile de prévoir des languettes à l'intérieur de
l'ouverture 11, la bague assurant sa solidarisation avec la
cuvette grâce à la présence des becs déformables.We could for example use a ring such as
described with reference to Figure 7 with a
Il est possible également de donner à la bague 25 une forme différente, notamment une forme tubulaire permettant de ménager un espace libre de poudre au voisinage de la sortie de l'allumeur pyrotechnique.It is also possible to give the ring 25 a different shape, in particular a tubular shape allowing create a powder-free space near the outlet of the pyrotechnic igniter.
